The largest part of the heart is the left ventricle. The left ventricle (lv)is the strongest part of the heart. If you think about it the lv is one of the most important chambers of the heart because it pumps the blood to the aortic sl valve which goes to the aorta. The aorta supplies the body with oxygen rich blood and it is very important that the body has oxygen without o we would not be able to function.

The human heart, like other animal hearts, is mainly muscle tissue. It also contains connective tissue in the valves, and is extensively vascularized (many blood vessels). The heart will begin beating in humans at around 6 weeks after conception and ordinarily will not stop until the person dies.

The entire heart is made of cardiac muscle tissue (that basically made the 4 cavities of the heart) and elastic (dense) connective tissue (valves)
